    en.wikipedia.org/wiki/Stability_theory

    Stability diagram classifying Poincaré maps of linear autonomous system ′ =, as stable or unstable according to their features. Stability generally increases to the left of the diagram. [ 1 ] Some sink, source or node are equilibrium points .

    en.wikipedia.org/wiki/Equilibrium_point...

    Stability diagram classifying Poincaré maps of linear autonomous system ′ =, as stable or unstable according to their features. Stability generally increases to the left of the diagram. [1] Some sink, source or node are equilibrium points.

  4. Saddle-node bifurcation - Wikipedia

    en.wikipedia.org/wiki/Saddle-node_bifurcation

    If < there are two equilibrium points, a stable equilibrium point at and an unstable one at +. At = (the bifurcation point) there is exactly one equilibrium point. At this point the fixed point is no longer hyperbolic. In this case the fixed point is called a saddle-node fixed point.

    en.wikipedia.org/wiki/Autonomous_system...

    Stability diagram classifying Poincaré maps of linear autonomous system ′ =, as stable or unstable according to their features. Stability generally increases to the left of the diagram. [1] Some sink, source or node are equilibrium points. 2-dimensional case refers to Phase plane.

  6. Linear stability - Wikipedia

    en.wikipedia.org/wiki/Linear_stability

    In mathematics, in the theory of differential equations and dynamical systems, a particular stationary or quasistationary solution to a nonlinear system is called linearly unstable if the linearization of the equation at this solution has the form / =, where r is the perturbation to the steady state, A is a linear operator whose spectrum contains eigenvalues with positive real part.

  7. Schreinemaker's analysis - Wikipedia

    en.wikipedia.org/wiki/Schreinemaker's_analysis

    A generic phase diagram with unspecified axes; the invariant point is marked in red, metastable extensions labeled in blue, relevant reactions noted on stable ends of univariant lines. This rule is geometrically sound in the construction of phase diagrams since for every metastable reaction, there must be a phase that is relatively stable. This ...

  8. Lyapunov stability - Wikipedia

    en.wikipedia.org/wiki/Lyapunov_stability

    In simple terms, if the solutions that start out near an equilibrium point stay near forever, then is Lyapunov stable. More strongly, if x e {\displaystyle x_{e}} is Lyapunov stable and all solutions that start out near x e {\displaystyle x_{e}} converge to x e {\displaystyle x_{e}} , then x e {\displaystyle x_{e}} is said to be asymptotically ...

  9. Homoclinic orbit - Wikipedia

    en.wikipedia.org/wiki/Homoclinic_orbit

    More precisely, a homoclinic orbit lies in the intersection of the stable manifold and the unstable manifold of an equilibrium. It is a heteroclinic orbit–a path between any two equilibrium points–in which the endpoints are one and the same. Consider the continuous dynamical system described by the ordinary differential equation
